std::array<uint32_t, 50> my_array;

  • A
    std::sort(my_array.begin(), my_array.end(),
    [](uint32_t a, uint32_t b) {
    return a < b;
    })
  • B
    lambda(uint32_t a, uint32_t b){
    return a < b;
    }
    std::sort(my_array.begin(), my_array.end(), lambda);
  • C
    std::sort(my_array.begin(), my_array.end(),
    lambda(uint32_t a, uint32_t b){
    return a < b;
    })
  • D
    lambda(uint32_t a, uint32_t b){
    return a < b;
    }
    std::sort(my_array.begin(), my_array.end(), &lambda);
